Evaluación de la sorción de boro en suelos aluviales

Abstract

[ES] En este trabajo se estudia la sorción de boro por suelos que difieren en su origen (cuencas de los ríos Gállego, Ebro y Jalón) y en su contenido en arcilla. La influencia del contenido de arcilla sobre los fenómenos de sorción de boro por suelos se manifiesta de manera más notable en los procedentes de las cuencas de los ríos Gállego y Jalón, cuyos contenidos de arcilla no son superiores al 30%, en tanto que, en los suelos de la cuenca del río Ebro, con contenido en arcilla superior al 25%, la influencia de este constituyente del suelo sobre la retención de boro no es tan marcada. Todos los suelos arcillosos llegan a retener un 72% del boro adicionado en tanto que cuando el contenido en arcilla es del 11 y 27%, la retención varía entre 30-16% y 60-50%, respectivamente. Se han calculado los valores de adsorción máxima y constante de unión aplicando la ecuación convencional y la modificada de Langmuir. Al aplicar la ecuación convencional de Langmuir se encuentra que, cuando el contenido de arcilla es superior al 20%, se manifiestan dos lugares de adsorción de boro. El primero a una concentración límite en la solución final de 1 ppm de boro, en tanto que el segundo lugar de adsorción se presenta a una concentración comprendida entre 4 ppm y 12 ppm. Los valores de adsorción para los lugares I y II guardan, dentro de cada cuenca, una cierta relación con el contenido de arcilla, al igual que la absorción total calculada. Estos mismos hechos se ponen de manifiesto cuando se elaboran los datos obtenidos por la ecuación modificada de Langmuir, con la excepción del suelo arcilloso de la cuenca del río Gállego, que presenta un tercer lugar de absorción, cuando la concentración de boro en la solución final es del orden de 6 ppm. Los valores correspondientes a adsorción máxima y constante de unión calculados según esa ecuación son más bajos que los obtenidos por la convencional de Langmuir. Se considera la posibilidad de utilizar los datos obtenidos en estos estudios para predecir la cantidad de boro a adicionar en los suelos, con objeto de evitar problemas de toxicidad debidos a este microelemento.

[EN] In this paper, the boron sorption by soils wich are different in origin (for belonging to vallery from Gallego, Ebro and Jalon rivers) in their clay content, is studied. The influence of clay content on this B sorption in these soils, is more clear in those belonging to the vallery of Gallego and Jalon rivers, in wich the clay contents are no higher than 30%. While the soils belonging to Ebro valley show a clay content higher than 25%, and for that reason the diferences among soils related to B sorption are not so notorious. All clay soils reach a 72% of boron added, when the content of this soil fraction is 11 and 27%, this retention value becomes between 30-16% and 60-50% respectively. Maximum adsorption and constant binding between soil and B are calculated by two equations, one the conventional Langmuir equation, and the other one the modified Langmuir when the clay content is higher than 20%, and the conventional Langmuir equation is applied to boron sorption values, it is detected two sites for the adsorption of this element. The I site takes place at a 1 ppm. B concentration in final solution, while the II site is related to a concentration comprehend between 4 and 12 ppm. B in final solution. As well B sorption values in sites I and II as total K2 for soil belonging to each valley, are related to the clay content exhibited by these soils. The same facts are obtained, when to the boron sorption values are analysed by the modified Langmuir equation, except with the clay soil from Gallego river, in which a third site sorption takes place in final solution there is a concentration of 6 ppm. B. In general, the values of K1 and K2 are lower than those calculated by the convencional equation Langmuir. It is considered the posibility to use the data obtained in this study for predicting the ammount of boron to be applied in soils, in order to avoid problems of toxicity due to this microelements after a fertilization trace.
